IMPROVEMENT m PLOWS.

Specification forming part of Letters Patent No. 130,196, dated August6, 1872.

Specification describing a Compound Turn- Plow and Subsoiler, inventedby EDWARD S. 000K, of Laurel Grove, in the county of Pittsylvania andState of Virginia.

The invention consists in a new mode of constructing a skeleton frame,and of attachin g the share thereto.

Figure l is a perspective view of the plow With the mold-board detached.Figs. 2, 6, and 7 are detail views of the mold-board. Fig. 3 is a sideelevation of the plow. Fig. 4 is a detail view of land-side with part ofthe foot of the frame. Fig. 5 is a bottom view of share and frame-foot.

A A represent the handles; B, the beam; 0, the skeleton frame, to whichthe plow-irons are attached; D, the land-side; E, the moldboard F, theshare; and G, the clevis. The skeleton frame 0 consists of the foot 0,standard c and the rearwardly curved and projecting flange 0 On the rearside of foot 0 is formed an angular recess, 0 which receives the angularofl'set d of land-side, which is also attached to foot by the ordinarybolt and nut (1 (1 By this lock-joint c d all upward or downwardvertical play of the landside is effectually prevented. The front ofstandard 0 is smooth and spirally concaved at C so as to transfer thetrash that gathers in front underneath and to one side, and cause it tobe turned under. On the forward edge of frame are serrations a andprojections a, which fit into corresponding projections and serrations ff of share. These prevent lateral movement of the share, while theshare-lip f which projects into a cavity, a (which is under the rightcorner of frame 0,) serves to take the strain off the fasteningshare-bolt and prevent vertical play. The mold-board E is constructedwith lateral projection e, which has a dovetailed screw-head, e, thatfits into a corresponding dovetailed groove, b, on the inner side offlange 0 the two being fastened by a clamp-screw, b On the lower part offrame 0 is a lateral stop, N, which receives the strain caused bypressure of sod against mold-board. Another fastening-bolt, D is shownto attach mold-board to frame; but it is not material, since thedovetailed joint b e and the stop b amply suffice for this purpose underall ordinary circumstances. The handles are both attached to land-side,but are then connected with frame .0 by a brace, H, which passesobliquely across from one to the other. This retains th e handles firmlyand rigidly in position, while their use in throwing the heavy plowabout cannot displace them out of their proper relation to the plowirons and beam. It also helps to support the force which is constantlybeing exerted against mold-board flange, and prevent it from being\vrenched out of its exact position. The clevis G consists of twoplates, 9 g, having perforations in a diagonal line, which brings thelowest perforation under the beam, where is placed a pin and hook toreceive the double-tree. This is a very cheap and efficient clevis, andcan be readily applied to or removed from any beam.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

1. The land-side D, provided with the angular offset or block (1, incombination with the foot (3, recess 0 said parts being secured togetherby the bolt and nut d d all constructed and fitted together as shown anddescribed; 2. The skeleton frame 0, consisting of the foot 0, standard 0and rearwardly curved flange adapted, with the share, to serve as asubsoiler, and, with the addition of the moldboard, as a turn-plow, asdescribed.
